PCT No. PCT/DE88/00252 Sec. 371 Date Oct. 11, 1988 Sec. 102(e) Date Oct. 11, 1988 PCT Filed Apr. 28, 1988 PCT Pub. No. WO88/09837 PCT Pub. Date Dec. 15, 1988.A device for the control of an open-end spinning element, including a pivoted control lever (4) is provided which is capable of assuming three different working positions. In a production position the control lever brings a first drive, running at production speed, into driving contact in the operation of the open-end spinning element. In a braking position the control lever brings a brake to act upon the spinning element. The control lever in a piecing position brings a second drive which runs at a lower speed than the first drive into driving contact with the open-end spinning element. At least the positions determining the production and the piecing position of the control lever are provided with a common control element, capable of being moved back and forth in the direction of movement of the free end of the control lever between at least two switching positions. The control element is provided with a stop element which determines at least the production or the piecing position of the control lever, depending upon the switching position (I, II) of the control element. The stop element is an integral part of the control element. The control element, in addition to movement in the direction of movement of the free end of the control lever, can also be moved transversely to the direction of movement of the free end of the control lever.
